ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 625,426, dated May 23, 1899.

Application filed March l, 1899.

To @ZZ whom, it 77mg/ concer-lt:

Beitknown that I, GAREET F. SPEER, acitizen of the United States, residing at'Canisteo, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Acetylene-Gas Generators; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to acetylene-gas generators; and the object is to simplify the bid-holder, showing the manner in which its coveren gages and is removed from the holder bythe flange in the gas-generating chamber.

In the drawings, 1 denotes the tank, and 2 the holder arranged within the tank and separated therefrom by a water seal. The bottom of the tank is preferably conical and is provided with a draw-off cock 3.

4 denotes a vertically-disposed chamber which contains water and acts as a scrubber. The upper end of this chamber is enlarged, as shown at 5, and is provided with two perforated diaphragms G and 7, between which is clamped a sponge S, which acts as a drier for the gas. i) denotes a perforated float situated within said scrubber-chamber. This float serves to break up the bubbles caused by the flowing of gas through theV scrubber, so as to present it in afine aerated condition to the drier. By this breaking up of the bubbles the sulfureted and phosphoreted hydrogen is nearly all liberated, and when t-he gas reaches the sponge or drier it is nearly pure and is rendered absolutely pure by passing through the drier.

10 denotes the water-overflow pipe, 'secured to the upper end of the tank, and 11 denotes the gas-outlet pipe, which has one end pro- Serial No. 707,394. (No model.)

j ecting upwardly through the tank above the water-level and the other end leading to the point of consumption.

12 denotes the generator-chamber, which is preferably provided with a tapering base having a draw-off cock 13. This chamber is provided near its lower end with an annular ange 14, having an upturned edge 15.

16 denotes a pipe which establishes coni- .munication between the generating-chamber and the scrubber-chamber, the two chambers havingthe same waterlevel.

17 denotes the carbid-holder, the upper end of which is provided with a cross-bar 18.

' 19 denotes a cover which tightly fits' the upper end of said holder and is provided with an annular inverted U shaped flange 20, Vwhich is adapted to coperate with the vertical'edge 15 of the flange 14.

21 denotes a rod the lower end of which is fixed to the cross-bar 18 and the upper end of which is screw-threaded and passes through a threaded har 22, held in position at the upper end of the generator-chamber by lugs 23.

In charging the generator-chamber the carbid-holder is rst filled with calcium carbid and its cap or cover forced firmly upon its open end. In this position the holder is forced downward through the water contained in the generating-chamber and the bar 22 engaged with the lugs 23 at the upper end of the chamber. Now when it is desired to generate the gas the rod 21 is screwed downward, thus bringing the U -shaped flange 20 into engagement with the upturned edge 15'of the annular flange 14 and forcing the holder away from its cover, thus allowing the water to come in contact with the calcium carbid and generate the gas,which passes through the pipe 16 into the scrubber 4, from thence through the drier, and out into the gas-holder.

To prevent the cover sliding too far upward on the rod 21 after it has been separated from the carbid-holder, l provide the rod With a stop-shoulder 24. Thus it will be seen that after the carbid-holder has been forced away from the cover this stop 24 will bear against the cover and hold the U-shaped flange down firmly against the upturned edge 15 of the flange 14 and prevent theescape of gas at that point.

It will of course be understood that various IOO changes in the form, proportion, and the ininor details of Construction may be resorted to with out departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the-invention, what is claimed, and desired to be secured by Letters Patent, is-

l. In an acetylene-gas generator, the oombination with the generatorchamber, of a carbid-holder adapted to be submerged within said Chamber, said holder being provided with a cover, and said chamber being provided With means for separating the cover from the holder when the latter is submerged Within the chamber, substantially as and for the purpose set forth.

2. In an acetylene-gas generator, the combination with the generating-Chamber having an annular flange arranged therein, of a earbid-holder having a cap or cover, provided with a U-shaped flange to engage the flange of the generator-chamber, anda rod fastened to the holder and extending through the cover thereof, and provided with a stop-shoulder,

lan annular flange provided with a vertical edge, and a pipe leadingfrorn said generator below said flange; -of a carbid-holder having a bar secured across its top, a cover for said holder having an inverted-U-shaped flange, a rod loosely engaged with said cover and fastened to the bar in the holder, a bar removf ably secured to the top of thel generator-chamber and provided with screw-threads to engage the upper threaded end of said rod, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
